  • 1.  C-SPOC - create volume group - missing last disk

    I have AIX 6.1 TL07 SP04 installed to LPARs on a couple of P770s.
    The storage is nSeries and we are presenting LUNs via NPIV.
    PowerHA v7.1.1. SP02

    I have installed PowerHA.
    I have configured cluster, nodes, networks, network interfaces, repository, and multicast IP.
    Verify and synch is ok.

    I now want to create my volume groups on the shared disks via CSPOC.
    I go to smitty cspoc - storage - volume groups - create a volume group - select either node
    It only gives me the option of selecting 5 out of the 6 disks. It sees hdisk 5-9 but not hdisk10.
    hdisk11 is my repository disk.
    If i go to smitty cspoc - storage - physical volumes - list all shared physical volumes - it shows all of the disks i would expect to see - hdisk5-11.

    I have compared hdisk10 with the rest of the disks and there is no configuration difference.

    I have another newly built cluster with the exact same issue.

    Any ideas?
    (I have also opened a PMR)

    since cspoc is not necessary for any lvm task, bugs sometimes stay undiscoverd in there for a long time. my personal opinion.

    I used the cl_mkvg command to work-around the issue.
    I've kept the PMR open as it's obviously still a bug in the pick-list in cspoc.
